Redis - standalone Redis Server

Warning: This document is old! It is likely wrong in some important way.

The official repository for Running Redis on Fly.io. Find the accompanying Docker image at flyio/redis.

Usage

This installation requires setting a password on Redis. To do that, run fly secrets set REDIS_PASSWORD=mypassword before deploying. Keep track of this password - it won’t be visible again after deployment!

If you need no customizations, you can deploy using the official Docker image. See fly.toml in this repository for an example to get started with.

Runtime requirements

By default, this Redis installation will only accept connections on the private IPv6 network, on the standard port 6379.

If you want to access it from the public internet, add a [[services]] section to your fly.toml. An example is included in this repo for accessing Redis on port 10000.

We recommend adding persistent storage for Redis data. If you skip this step, data will be lost across deploys or restarts. For Fly apps, the volume needs to be in the same region as the app instances. For example:

cmd

flyctl volumes create redis_server --region ord

To connect this volume to the app, fly.toml includes a [mounts] entry.

[mounts]
source      = "redis_server"
destination = "/data"

When the app starts, that volume will be mounted on /data.

Cutting a release

If you have write access to this repo, you can ship a prerelease or full release with:
